• NetPochi KeyDown Event, IsInputKey not working (C#)

  (C#, VS 2005) - I have a form, with a few radiobuttons on it. I want to do some stuff when the arrow keys are pressed but the event isn't raised. I found on MSDN that you should override IsInputKey, but I did that and it doesn't work (IsInputKey is never called). Another problem (may have something to do with it) is that i can't find a way to stop the arrow keys from scrolling through the radiobuttons. thanks in advance It works actually but thats not what i need, I want the event fired multiple times when the user holds down the key longer. Edit: I added other controls and disabled the tabstops for the radiobuttons, now it works :/ make sure your set the forms key ...Show All

• MicMit I can't figure this "Enter" thing out! Please help.

  Ok, so I am creating a web browser. Everything is fine and dandy, except I wanted the capability of the user pressing "Enter" after they type in the URL instead of having to go click on "GO" button. Thats nice... So I go to the properties of the combobox, select "Keydown" and create a new keydown event. In that event, I write: webBrowser1.navigate(combobox1.Text); I run the program... and It works alright! However, it automaticly tries to connect the the URL before I even get it typed... So by the time I type in www.yahoo.com , it's already navigated there without me pressing the enter key. This is a neat little thing, but I don't want it to work that way. Is there some kind of Break I can use to stop the URL in the U ...Show All

• pst_grant Performance of a fully transparent brush

  I have a simple performance question about transparency (.NET 2.0, WinXp). Does GDI+ handle zero alpha transparency as a special case What is the cost of graphics.FillRectangle(Brushes.Transparent, myRectangle) compared to graphics.FillRectangle(someSemiTransparentSolidBrush, myRectangle) and graphics.FillRectangle(myFullyOpaqueSolidBrush, myRectangle) I ask because I am designing an application with possibly thousands of small interactive outlined shapes. I only want to fill the selected ones and from a design point of view it would be more elegant to fill the shapes with a zero alpha brush instead of checking the state of the shape when drawing it.

• houtexwebdev Is it possible to simulate a property for databinding on an object using ITypedList

  Is it possible to simulate properties on an object and have the simulated property bound to a windows form control I have seen examples using ITypedList to do this. But all the samples simulate the property on a collection of business objects and never on the business object itself. When i tried to do this on an object by adding a new property to the PropertyDescriptorCollection being returned, i get an ArgumentException when setting the datasource saying "Cannot bind to the property or column Company on the DataSource.

• Rod at Work Reading data from another form

  Everything I have read on the web says I can do this. I have followed the setup of others that seemed to have solved their issue, but it still fails for me. I want to read data from a textbox on form1 from form2. Since I declared frmVendor_list as public and I set the textbox1 on that form to have a modifier of public, I assumed I would be able to access the text in the textbox. But it will not build, throws an error 'Textbox1 is not a member of system.windows.forms.form If I add the line: dim vendor_list as form1 right above the call to the textbox from form2 and refer to the textbox as vendor_list.textbox1.text - the error goes away and it compiles.

• WayneSpangler How to check Windows Form is completely shown on the screen

  Actually the reason for this is: i want to do printscreens within my application(like after i press a button on my form, this button press will run a method with printscreen function), therefore at first i had Application.DoEvents(); System.Threading.Thread.Sleep(1000); but i read up on application.doevents() and there is an issue that it may go into an event twice.. Is there a way to check when the windows form is completely loaded or repainted as i run my application Or is there suggestions to let the application wait while continuing to load cos if using thread.sleep only, the whole application will pause and the form loading will also pause. Or is there any alternative to application.doevents() Let me clarify that i am not using this ...Show All
